Determination of the detonation velocity emulsions explosives in the different thermal condition

Detonation velocity is the velocity at witch the chemical reaction zone propagates trough a given explosive. It is one of the most important detonation parameters. Bearing in mind the fact that detonation velocities of know high explosives may reach nearly 10 mm/microsecond, the experimental determination of the detonation velocity is not easily achieved. However, when compared to the other detonation parameters, its accomplishment represents the least complicated task. The determination of the detonation velocity is based upon the measurement of the time interval needed for the detonation wave to travel a known distance through the explosive being tested. The measuring equipment used for the determination of the detonation velocity should provide the detection of the arrival of the detonation wave using suitable velocity probes, the measuring of the very short time-intervals (on a microsecond scale) needed for the detonation wave to travel a known distance through the sample between two velocity probes. Velocity of detonation shall be determined at the minimum diameter placed on the market, or the minimum diameter recommended by the manufacturer. Experimental determination of the detonation velocity emulsions explosives in the different thermal condition to direct attention to change detonation velocity with change temperature explosives.
